Update on Paris Sewer Museum?

This specific question was asked and answered a little less than a week ago. Here is the answer:

I was curious too, so I called the museum's phone number (01 53 68 27 81) and the fellow who answered the phone said maybe it would open in December 2020, but he was far from confident on that date.
Sounds like a possibility for visiting in 2021 or beyond.

Thank you Sammy. That is disappointing.

Thanks for bringing this up - I am going in May and was hoping to make the sewers part of my trip. Really disappointed that they probably won't be open then!
